Attractants for bactrocera latifrons(Hendel)

Abstract

Compositions and combinations of alpha-ionol and cade oil are effective attractants for Bactrocera latifrons (Hendel) fruit flies. By attracting adult males to field traps or baits, the attractants provide a means for detecting, surveying, monitoring, and controlling this agricultural pest.

What is claimed is: 
     
       1. An attractant composition for male Bactrocera latifrons (Hendel) fruit flies, which comprises a mixture of alpha-ionol and cade oil. 
     
     
       2. The composition of claim 1 wherein the mixture of alpha-ionol and cade oil comprises a volumetric ratio range of about 12:1 to 1:3 alpha-ionol:cade oil. 
     
     
       3. A lure for attracting Bactrocera latifrons (Hendel) fruit flies, which comprises a dispenser means which contains alpha-ionol and cade oil. 
     
     
       4. The lure of claim 3 wherein said dispenser means contains a mixture alpha-ionol and cade oil. 
     
     
       5. The lure of claim 3 wherein said dispenser means comprises one or more dispensers wherein alpha-ionol and cade oil are separately released in sufficient proximity to provide an effective attractant amount of a vapor blend of alpha-ionol and cade oil. 
     
     
       6. The lure of claim 3 wherein said dispenser means is located within a trapping means for said fruit flies. 
     
     
       7. The lure of claim 3 which further includes a means for controlling Bactrocera latifrons fruit flies. 
     
     
       8. A trapping system for detecting, monitoring, attracting or controlling Bactrocera latifrons (Hendel) fruit flies, which comprises a dispenser means located within a trapping means which provides an effective attractant amount of alpha-ionol and cade oil. 
     
     
       9. The trapping system of claim 8 wherein said dispenser means contains a mixture of alpha-ionol and cade oil. 
     
     
       10. The trapping system of claim 8 wherein said dispenser means comprises one or more dispensers wherein alpha-ionol and cade oil are separately released in sufficient proximity to provide an effective attractant amount of a vapor blend of alpha-ionol and cade oil. 
     
     
       11. A method for attracting Bactrocera latifrons (Hendel) fruit flies, which comprises placing in an area where said fruit flies are to be attracted a dispenser means which provides an effective attractant amount of alpha-ionol and cade oil. 
     
     
       12. The method of claim 11 wherein said dispenser means contains a mixture of alpha-ionol and cade oil. 
     
     
       13. The method of claim 11 wherein said dispenser means comprises one or more dispensers which release alpha-ionol and cade oil to provide an effective attractant amount of a vapor blend of alpha-ionol and cade oil. 
     
     
       14. The method of claim 11 which further includes a means for controlling Bactrocera latifrons fruit flies.
